Autodesk RVT_ELEC_01101 Autodesk Certified Professional in Revit for Electrical Design Exam Practice Test

In Autodesk Revit MEP, conduit systems can be represented in plan views using either detailed or single-line symbology. The Single Line Symbology display setting is used for schematic or simplified representations — often in electrical riser or distribution diagrams.

The setting that controls whether conduits display in single-line or detailed form is found in the Type Properties of the conduit family, not in Object Styles or Electrical Settings. Specifically, it is accessed by selecting a conduit in the model and navigating to:

Properties Palette → Edit Type → Single Line Symbology

From there, users can define how fittings, rise/drop symbols, and conduits themselves are represented in single-line schematic mode. Adjusting this type parameter affects the graphical display for that conduit type throughout all applicable views where single-line graphics are used.

According to the Autodesk Revit MEP User’s Guide (Electrical Systems → Conduit Systems section):

“The conduit type properties define the graphical representation in single-line drawings. By editing the Single Line Symbology in the Type Properties dialog, designers control how the conduit and fittings appear in plan views.”

This parameter is especially important in electrical documentation where simplified representations are required for coordination and electrical diagrams.

The parameter “Lighting Calculation Luminaire Plane: Not Computed” in the Space Properties dialog appears when Revit cannot perform a lighting calculation because no valid lighting fixtures are present within that defined space.

According to the Autodesk Revit MEP User’s Guide (Chapter: Spaces and Lighting Analysis):

“Lighting calculations are performed based on the luminaire data available in the space. If no light fixtures are present, the parameter ‘Lighting Calculation Luminaire Plane’ displays as ‘Not Computed’. Revit requires at least one hosted or ceiling-mounted lighting fixture with a valid light source to calculate illumination.”

In this case, although the space has defined reflectance values (ceiling, wall, and floor) and a lighting calculation workplane height (2’-6”), Revit cannot compute the Luminaire Plane because the software has no lighting geometry to reference for the photometric analysis.

Explanation of incorrect options:

A. Missing IES file: This would cause inaccurate photometric output, but not “Not Computed.”

C. Lights not circuited: Circuiting affects load summaries, not lighting calculations.

D. Lights at different elevations: Revit still computes the average luminaire plane even with varied fixture heights.

Thus, the lighting calculation is not computed simply because no lighting fixtures are placed in the space.

In Autodesk Revit, Design Options are used to explore multiple design alternatives within the same project environment. This feature is often employed by electrical designers to model different lighting layouts, circuiting approaches, or equipment placements without duplicating the entire project.

When an additional design option is created within the same option set, and the designer needs to include all the same elements that already exist in another design option, Revit offers two effective ways to duplicate these elements while preserving their type, parameters, and host relationships.

According to the Autodesk Revit MEP User’s Guide (Chapter: Working with Design Options), it clearly describes:

“To create a copy of an existing design option within an option set, open the Design Options dialog box, select the desired option, and click Duplicate. This creates a new option containing identical elements and maintains their relationships and constraints.”

This confirms Option C as correct because duplicating an option from the Design Options dialog automatically replicates all its elements into the new design option within the same option set.

Furthermore, the guide continues:

“Alternatively, when working with a specific design option view, you can use the Copy to Clipboard and Paste Aligned > Aligned to Current View commands to duplicate selected elements into another active design option. These elements are placed in the same location and remain associated with the new design option.”

This validates Option D as the second correct method, allowing manual duplication of elements between options while keeping spatial alignment intact.

Other options listed are incorrect for the following reasons:

A (Drag and Drop) is not supported between design options; it only works between views in the same option.

B (Reveal Hidden) only displays hidden elements; it doesn’t expose design option geometry for copying.

E (Add to Set) transfers elements into the same design option set, not between individual design options.

Therefore, the two valid and Autodesk-confirmed methods to duplicate all elements between design options are:

C. Duplicate from Design Options dialog, and D. Copy/Paste Aligned to Current View.

In Autodesk Revit Electrical Design, revisions are managed using the Sheet Issues/Revisions dialog to track changes and document issuance phases, such as “Issued for Bid” or “Issued for Construction.” The revision schedule on the title block automatically reflects this data when configured correctly.

According to the Revit MEP User’s Guide (Chapter 48 “Construction Documentation – Managing Sheets and Revisions”):

“Revisions define a record of changes issued with sheets. To display a revision in the title block, it must first be created in the Sheet Issues/Revisions dialog, assigned a description, and set to be shown in the revision schedule.”

Here’s how the process works step-by-step:

1️⃣ Add a new revision in the Sheet Issues/Revisions dialog.

Navigate to View tab → Sheet Composition panel → Revisions.

Add a new revision line entry (this creates a new revision record).

2️⃣ Change the Description to “Issued for Bid”.

In the same dialog, edit the Description field to reflect the issuance purpose.

3️⃣ Select Shown in Revision Schedule next to “Issued for Bid”.

Check “Show” in the Revision Schedule column so it will appear in the title block’s revision schedule table.

4️⃣ For each sheet to be issued, click Edit next to Revisions on Sheet in the Properties palette.

In the Properties palette, under Identity Data, click Revisions on Sheet → Edit and assign the “Issued for Bid” revision only to the sheets being released.

This ensures only the selected sheets display the “Issued for Bid” entry, maintaining proper control over which drawings are issued while others remain unaffected.

As described in the Smithsonian Facilities Revit Template User’s Guide:

“Revision schedules are dynamically linked to sheet issue data. Designers can show or hide revisions on a per-sheet basis by editing ‘Revisions on Sheet’ from the Properties palette.”

The exhibit shown displays the Type Properties dialog box for a System Family: Floor Plan view type. Within the “Identity Data” group, there are two critical parameters that govern the behavior of new views created from this view type:

“View Template applied to new views”

“New views are dependent on template”

According to Autodesk Revit’s documentation in the Revit MEP User’s Guide (Chapter 48 “Views and View Templates” and Chapter 49 “Preparing Construction Documents”):

“When a view template is assigned to a view type through the Type Properties dialog, any new view created from that view type automatically receives the defined view template. This ensures consistent visibility, graphics, and discipline settings for all new views.”

In this image, the parameter “View Template applied to new views” is set to Electrical Plan, and “New views are dependent on template” is checked. This means that any new floor plan created using this type will automatically have the Electrical Plan template applied, and the view will be dependent on that template, meaning it inherits all its visibility and annotation control settings.

This ensures that all electrical floor plan views generated are standardized and visually consistent, a fundamental practice in Revit Electrical Design workflows, as described in the Smithsonian Facilities Revit Template User’s Guide:

“Assigning a default view template to a view type (e.g., Electrical Plan) ensures every new view created follows organizational and graphical standards without manual setup.”

Option A matches this behavior exactly.

Option B is incorrect** because Revit does not create a new template automatically.

Option C is incorrect** because duplication of an existing view does not reassign templates by type.

Option D is incorrect** because dependent view creation requires a specific “Duplicate as Dependent” command, not this setting.

In Autodesk Revit, particularly for electrical and MEP design disciplines using a workshared model, the command “Reload Latest” allows a designer to see changes made by other users without saving or publishing their own work to the central model. This tool ensures that while the designer continues to work locally, their environment stays updated with the latest modifications made by colleagues.

According to the Autodesk Revit MEP User Guide (Chapter 54 – Working in a Team), under the section Loading Updates from the Central Model, it states:

“As you work, you can see the changes other team members have made to the project after they have been synchronized with the central model. You can load updates from the central model without publishing your changes to the central model.

In your local file, click Collaborate tab ➤ Synchronize panel ➤ (Reload Latest).”

This confirms that the Reload Latest command refreshes your local file with any modifications from the central file that others have synchronized, but it does not send your local changes back. It is a critical feature for coordination in a team environment, especially when multiple designers—such as electrical, mechanical, and structural engineers—are contributing simultaneously to a shared BIM model.

By contrast:

A. Relinquish All Mine only releases ownership of elements but doesn’t update the local model.

C. Manage Worksets is for controlling visibility and editability of worksets.

D. Worksharing Display visually identifies ownership and status but doesn’t refresh model data.

Therefore, when an electrical designer needs to review updates from others (for example, when a lighting layout needs coordination with architectural ceiling adjustments), the proper workflow is to use Reload Latest, ensuring all new information from the central model appears instantly without saving or affecting their current unsaved edits.

In Autodesk Revit Electrical Design, ensuring that all electrical connectors are properly connected to circuits is critical to obtaining accurate load summaries and panel schedules. When nearing project completion, designers must confirm that every load (e.g., lighting fixture, power receptacle, or equipment) is associated with a circuit.

The Show Disconnects command is specifically designed to identify any electrical components whose connectors are not associated with a circuit or power system.

According to the Autodesk Revit MEP User’s Guide (Chapter: Electrical Systems – Checking Electrical Circuits):

“The Show Disconnects tool allows designers to visually identify elements in a project that contain electrical connectors not currently assigned to any circuit. Using this tool, Revit highlights unconnected components, helping to ensure load summaries and panel schedules accurately reflect all modeled elements.”

The command is found under Analyze tab ➤ Electrical panel ➤ Show Disconnects. It highlights any devices—such as lighting fixtures, receptacles, or equipment—that are not circuited, enabling correction before final load calculations are performed.

Other options explained:

A. Check Circuits: Verifies that existing circuits are complete, but it does not identify unconnected components.

B. System Browser: Lists systems hierarchically but does not flag disconnected devices.

C. Circuit Schedule: Displays circuit data only for connected components.

Hence, to identify unconnected elements before finalizing design documentation, the correct tool is Show Disconnects.

In Autodesk Revit, the Collaborate tab provides the tools necessary for managing multi-user worksharing environments. The Synchronize with Central command allows users to save their local changes back to the central model. However, this command becomes disabled under certain conditions — most notably when the user is currently working directly within the central file rather than a local copy.

The Autodesk Revit User’s Guide – Worksharing and Collaboration section clearly explains this behavior:

“When you open the central file directly, the Synchronize with Central option is unavailable because all edits are already in the central file. Worksharing operations such as borrowing, relinquishing, or synchronization only apply to local copies created from the central model.”

This rule ensures that the integrity of the central model is preserved and that no user directly edits or synchronizes within it, preventing potential file corruption. In normal collaborative workflows, users open local copies of the central model. The local files maintain an editable subset of elements while allowing synchronization and relinquishing operations.

Thus, the disabled Synchronize with Central button (as shown in the exhibit) indicates that the designer is currently in the central model, not a local copy. Since synchronization is unnecessary in this state — all changes are automatically applied to the central file — the command is grayed out.

In Autodesk Revit Electrical Design, when an electrical designer attempts to control a receptacle (an Electrical Fixture family) with a switch (a Lighting Device family) as part of a switch system, Revit will only allow this connection if the receptacle’s family has been configured as Switchable within the Family Editor.

According to the Autodesk Revit MEP User’s Guide (Chapter 17 – “Electrical Systems”):

“Revit allows you to add elements such as lighting fixtures or receptacles to a switch system only if the family includes a switchable connector. The ‘Switchable’ parameter must be enabled in the Family Editor to allow this connection.”

This means that for the receptacle shown in the exhibit to appear as an available component for switching, the Electrical Connector within its family must have the Switchable property checked. This parameter is found under:

Family Editor → Select Connector → Properties Palette → Electrical - Data → Switchable.

If this option is not enabled, Revit treats the receptacle as a standard unswitched outlet and will not display it in the switch system creation dialog. Once the option is checked, the designer can reload the family into the project and associate it with a switch system normally.

Additionally, the Smithsonian Facilities Revit Template User’s Guide explains this concept as follows:

“To associate receptacles with lighting switches, ensure that the receptacle family has a switchable connector. Without this setting, the device will not appear as an assignable component to a switch system.”

This distinction is important in residential electrical modeling, where switched receptacles are common for plug-in lamps. Lighting circuits can include both Lighting Fixtures and Switchable Receptacles when the family configuration supports it.

Incorrect Options Explanation:

A. A switch system not being created is irrelevant — the issue occurs before system creation.

C. Being on the same circuit doesn’t affect switchability; it affects electrical load connection.

D. Incorrect — Revit supports switchable receptacles if properly configured.

Therefore, the correct answer is B. The receptacle’s “Switchable” option is not selected within the family editor.

In Autodesk Revit Electrical Design, the Project Browser can be customized to organize views according to disciplines, levels, and view types using the Browser Organization Properties dialog box. This feature allows electrical designers to create structured view hierarchies that align with project standards and simplify navigation — especially in multidisciplinary projects.

According to the Revit MEP User’s Guide (Chapter 41 “Browser Organization and View Management”):

“Browser organization defines how project views are grouped and displayed in the Project Browser. You can customize sorting by Discipline, Level, View Type, or any parameter applicable to views.”

In the given exhibit, the Project Browser structure shows views grouped first by discipline (“Coordination,” “Electrical”), then by level (“Level 1,” “Level 2”), and finally by view type (e.g., “Floor Plans,” “Ceiling Plans”). This organization allows the electrical designer to isolate MEP-related views while maintaining logical grouping under each building level.

To achieve this layout, the designer must apply the following browser organization setup in the Browser Organization Properties dialog box:

1️⃣ Group by: Discipline – creates top-level folders such as Architectural, Structural, Electrical, etc.

2️⃣ Then by: Associated Level – organizes each discipline into subfolders based on floor levels (Level 1, Level 2, etc.).

3️⃣ Then by: Family and Type – further organizes the level folders into view categories (e.g., Floor Plans, Ceiling Plans).

This configuration is supported by the Smithsonian Facilities Revit Template User’s Guide:

“Grouping by Discipline, Level, and View Type provides logical organization for MEP coordination, facilitating efficient access to electrical floor and ceiling plan views.”

Sorting by View Name (Ascending) ensures consistent alphabetical listing under each category.

In Autodesk Revit MEP Electrical Design, the System Browser is used to analyze and verify electrical systems, including panelboard connections, circuit hierarchies, and connected loads.

From the exhibit, the Properties palette shows that the selected equipment is a Lighting and Appliance Panelboard (208V MLO, 100A), named P4. To determine the parent panel that feeds Panel P4, we refer to the System Browser, which organizes the entire electrical distribution network hierarchically under the Electrical discipline.

In the System Browser on the right, under the Electrical category, we can observe that Panel P4 is nested directly under Panel P2. This organization indicates that P4 is circuited to (or fed from) Panel P2.

According to the Revit MEP 2011 User’s Guide, Chapter 4, “Electrical Systems—Using the System Browser,” it states:

“The System Browser displays electrical systems in a tree structure. Each subpanel or device listed beneath a main panel is connected to that panel through an electrical circuit. When a panelboard appears under another, it indicates the subpanel is fed from that parent panel.”

This is further reinforced in Smithsonian Facilities Revit Electrical Template Documentation (April 2021), Section 8.3 “Documentation Views,” which describes:

“Panel schedules and browser hierarchies show the distribution sequence. Subpanels appear indented beneath their source panel, indicating electrical dependency and circuit assignment.”

Therefore, by interpreting both the Revit interface and Autodesk’s documentation, Panel P4 is a subpanel connected to Panel P2, confirming that its electrical feed is assigned from Panel P2.

Final Verified Answer: B. Panel P2

In Autodesk Revit Electrical Design, each electrical family (such as a receptacle, lighting fixture, or equipment) can contain one or more connectors that define how it interacts with the electrical system. The Load Classification parameter determines how the connected load is categorized in electrical schedules and load calculations (e.g., Lighting, Power, Receptacle, Other).

When a family’s Type Parameter Load Classification does not display correctly (e.g., it shows “Other” instead of “Receptacle” after being circuited), the issue lies in the power connector’s internal parameter not being linked to the family-level “Load Classification” parameter. Revit uses the connector’s classification to determine the load type when it is connected to a circuit — if the connector isn’t associated, the classification defaults to “Other.”

According to the Autodesk Revit MEP User’s Guide (Chapter: Electrical Systems – Creating Electrical Families), it specifies:

“To control how a component reports its connected load type, associate the power connector’s Load Classification parameter with a corresponding Family Parameter. This ensures the load classification in the circuit matches the family definition, rather than defaulting to ‘Other.’ To correct existing families, edit the family in Family Editor, select the connector, and associate its Load Classification parameter with the family’s Load Classification type parameter. Then reload the family into the project.”

This confirms that the correct approach is to edit the family and create or link the Load Classification parameter to the connector’s Load Classification field. Merely changing the connector value (option C) won’t ensure dynamic synchronization between the family type and circuit. Deleting and re-adding the connector (option B) won’t automatically create that link. Option D (editing through the System Browser) modifies instance-level data, not family associations.

Hence, the correct and permanent fix is:

Open the family in the Family Editor.

Select the power connector.

In the Properties palette, click the small Associate Family Parameter button (⚙️) next to Load Classification.

Link it to the family’s Load Classification parameter.

Save and reload the family into the project.

The exhibit shown in the image is taken directly from the Revit MEP Electrical Systems workspace, specifically from the Parallel Conduits command interface. This dialog box appears when the designer activates the Place Parallel Conduits tool in the Systems tab → Electrical panel → Conduit dropdown → Parallel Conduits.

In this interface, the designer can specify:

Horizontal Number / Offset – defines how many conduits will be created horizontally and their spacing.

Vertical Number / Offset – defines how many conduits will be created vertically and their spacing.

Bend Radius Options:

Same Bend Radius – all conduits use identical bend radii.

Concentric Bend Radius – conduits bend concentrically around a common center point.

According to Autodesk’s Revit MEP 2011 User’s Guide (Chapter 18, Electrical Systems – Conduit Layout):

“The Parallel Conduits tool allows you to create multiple conduits side-by-side at the same time.

You can specify the number of conduits horizontally and vertically, as well as the offset between them.

You can also define whether bends have the same bend radius or concentric bend radii.”

— Revit MEP User’s Guide, Electrical Systems, Section: Conduit Layout

This tool is used when electrical designers need to route groups of conduits that run in parallel—such as power and data conduits running between panels or equipment racks.

The Concentric Bend Radius option (as shown in the exhibit) ensures all conduit bends share a common center, which is critical for maintaining uniformity in conduit sweeps and avoiding clashes during coordination.

Therefore:

A. Add Cable Tray – incorrect; the cable tray tool is separate and does not use bend radius options.

C. Array Conduit – incorrect; arraying is a different geometric function not specific to conduit routing.

D. Place Multiple Pipe – incorrect; applies to mechanical piping systems, not electrical conduits.

The display of Concentric Bend Radius, Horizontal Number, Vertical Number, and Offset confirms that the designer is using the Parallel Conduit placement tool.

In Autodesk Revit, a drafting view is a 2D view that contains detail information not directly associated with the model. When an electrical designer needs to reuse a drafting view from another project (for example, standard details or symbols), the correct method is to use the Insert Views from File command under the Insert tab.

The Autodesk Revit MEP User’s Guide – Chapter 48 “Detailing” (page 1072) describes the process as follows:

“Inserting a Drafting View from Another Project

Click Insert tab ➤ Import panel ➤ Insert from File drop-down ➤ Insert Views from File.

In the Open dialog, select a project file, and click Open.

The Insert Views dialog opens, displaying all the views that are saved in that project.

Select the desired drafting views and click OK.”(Revit MEP User’s Guide, p. 1072)

This command imports the drafting view into the current Revit model while preserving annotations, filled regions, detail components, and text. It ensures that any standard electrical symbols, notes, or schematics created previously can be directly reused without rebuilding the detail from scratch.

If any duplicate type names exist, Revit automatically uses the types and properties from the current project, displaying a warning if necessary.

“Revit MEP creates a new drafting view with all the 2D components and text. If you have duplicate type names, the type name and properties from the current project are used.”

(Revit MEP User’s Guide, p. 1072)

Supporting Documentation Extracts:

“Saving Drafting Views to an External Project

Select a drafting view in the Project Browser.

Right-click the view name, and click Save to New File.”(Revit MEP User’s Guide, p. 1071)

“The saved project can then be used later to insert drafting views into another Revit project using Insert Views from File.”

(Revit MEP User’s Guide, p. 1072)

In Autodesk Revit MEP, when working with electrical circuits, Revit visually differentiates elements based on their circuit membership and active selection during the circuit editing process. In the Edit Circuit mode, the software highlights elements connected to the active circuit in full color (black), while other electrical devices not part of that same circuit appear in halftone (gray).

In the exhibit, one receptacle appears in black, while the other is shown in gray (halftone). This indicates that only one of the receptacles is currently included in the circuit being edited, while the other receptacle belongs to a different circuit or has not yet been assigned to any circuit.

According to the Autodesk Revit MEP User’s Guide (Electrical Systems – Circuits section):

“When editing a circuit, the components that belong to the selected circuit are highlighted in the active color, while other elements in the view appear in halftone. Devices that are not on the same circuit will not be shown as connected or editable until added to the current circuit.”

Therefore:

The black receptacle is the one actively included in the selected circuit.

The gray (halftone) receptacle is not on the same circuit and thus not active for editing.

This visual cue is Revit’s way of helping the designer distinguish between circuit connections when adding or managing electrical devices.

In Autodesk Revit for Electrical Design, when a designer creates a panel schedule, the default name of the panel schedule view is automatically derived from the Panel Name parameter of the Electrical Equipment family to which the circuits are assigned.

According to the Revit MEP User’s Guide (Electrical Systems section: Panel Schedules):

“When you create a panel schedule, Revit uses the Panel Name parameter of the electrical equipment to define the default schedule name. The Panel Name identifies the distribution panel that supplies the circuits. This name appears in both the Panel Schedule view and in circuit information tags.”

— Revit MEP User’s Guide, Chapter 17: Electrical Systems – Panel Schedules

The Panel Name is a critical electrical equipment instance parameter located in the Electrical – Circuiting group of properties.

It appears in both the Electrical Equipment Properties Palette and the Panel Schedule Header. This name can later be modified manually, but by default, it directly controls the naming convention of the generated schedule.

In contrast:

A. Type Mark — identifies types within the family for documentation and does not control schedule naming.

B. Mark — a unique instance identifier often used for tags, but not for panel schedule view naming.

C. Description — provides descriptive text only for documentation or labeling.

D. Panel Name — correctly defines and drives the default schedule view name for panels and circuits.

When a panel (electrical equipment) is placed in the model and circuits are connected, Revit generates a new Panel Schedule View automatically titled using the value entered in the Panel Name field (e.g., “Panel LP-1”). This ensures consistency between the modeled equipment and the schedule documentation.

Verified Reference Extracts from Revit for Electrical Design Documentation:

Autodesk Revit MEP User’s Guide (2011), Chapter 17: Electrical Systems – Creating and Editing Panel Schedules:

“The name of the panel schedule view is determined by the Panel Name property of the electrical equipment.”

Revit MEP Electrical Design Training Manual, Module: Electrical Equipment and Panel Schedules:

“Panel Name is used by Revit as the default identifier for any panel schedule view created for that equipment.”

In Revit Electrical Design, the Selection Box tool is used to quickly isolate and display selected components in a cropped 3D view. When an electrical designer selects conduits or devices in a model and chooses Selection Box from the Modify tab, Revit automatically generates a 3D view bounded tightly around the selected elements, helping coordinate routing in confined or congested spaces.

According to the Revit MEP User’s Guide under “Creating 3D Views”:

“Use the Selection Box tool to create a 3D view that isolates selected elements. Revit automatically crops the view extents to the selected geometry.”

This feature is critical in multidisciplinary coordination because it allows the electrical designer to review specific conduits, cable trays, or lighting paths in context without manually adjusting view boundaries.

In contrast:

Default 3D View (Option B) shows the entire model.

Scope Box (Option C) controls view extents in 2D views or view templates, not instant isolation.

Section Box (Option D) is manually adjusted within an existing 3D view but does not automatically generate a cropped view around selected elements.

Therefore, the Selection Box is the correct and most efficient tool for this task.

In Revit Electrical, Demand Factors are applied through Load Classifications to compute an Estimated Demand Load rather than simply summing connected loads. The documentation states: “You use demand factors to adjust the rating of the main service… Demand factors are assigned to load classifications, and load classifications are assigned to device connectors. The estimated load for a device is calculated by multiplying the load by the demand factor. … The panel schedule can also display the load for each load classification.”

In the exhibit’s Demand Factor definition (for the Motor classification), the Calculation method is By quantity with Total at one percentage selected. Two quantity ranges are defined: 0–5 items at 100% and 5–unlimited at 50%. An additional checkbox adds an extra fixed load of 5000 VA to the calculated result. (This follows Revit’s behavior of applying the selected demand factor to the connected load and then adding any specified additional load to the result for that classification.)

Panel B feeds only panels E and F. The connected motor loads downstream are:

Panel E: 20 kVA + 10 kVA = 30 kVA

Panel F: 5 kVA + 5 kVA + 10 kVA = 20 kVA

Total connected motor load on B = 30 + 20 = 50 kVA (five items).

Because five items fall in the 0–5 range at 100%, the demand factor is 100% → 50 kVA. Per the definition, add an additional load of 5000 VA (5 kVA) to the calculated result:

Demand Load on Panel B = 50 kVA × 100% + 5 kVA = 55 kVA.

Therefore, the correct choice is 55 kVA.
